CONSERVATIVE Party chiefs will oust lame duck British Prime Minister Theresa May within the year.

May’s gamble of calling an early election has backfired disastrously for the party and the 60-year-old woman cannot survive, The Sun reported.

Her axing will be delayed to allow crucial Brexit negotiations to begin but her sacking will come after Christmas.

Humiliated party sources believe that Foreign Secretary Boris Johnson, Home Secretary Amber Rudd (who only held her seat by 300 votes) and Secretary of State for Exiting the European Union David Davis are the most suitable replacements and are being sounded out, Telegraph UK reported.
